fins are absent. The vertebrae count is low and range within 17 – 19. The first body spinules appear at the ventral side of the larvae during preflexion and usually spread fast over the entire body, sometimes this may be delayed or no spreading occurs at all. The pigmentation is initially restricted to the area above gut, brain and the yolk sac, but covering the head and trunk before flexion. There is no distinct pelagic juvenile stage.

•  Canthigaster capistrata Meristics: Dorsal rays:

9 – 10

Anal rays:

8–9

-- Morphology: The body is moderately deep. No fin spines are present. The head profile is concave and the jaws are protuberant, which was a prominent characteristics in the studied specimen.

-- Reference: MOURA and CASTRO (2002); TORTONESE (1986e);

-- Reference material: 1 specimen; 04/99: S13 (P89248);

-- Distribution: The only specimen was caught at a neritic station southwest of Gran Canaria at a depth of 33 – 53 m during night in spring.

•  Sphoeroides sp. The body is moderately slender. The dorsal and anal fins are opposite in position. No pelvic fins develop. No information of pigmentation development is given, so no verification of species identification can be done. Most probable the specimens are Sphoeroides pachygaster (MÜLLER and TROSCHEL, 1848). In the studied specimens the body spinules were well developed (Figure 74).

-- Reference: LYCZKOWSKI-SHULTZ (2006); TORTONESE (1986e);

-- Reference material: 8 specimens; 11/97: S7 (P89252); S13 (P89253); S16 (P89249-251); 11/00: S1 (P89256); S11 (P89254-255);

-- Distribution: Specimens were only caught in autumn mainly at neritic stations. So southwest of Gran Canaria at a depth of 24 – 57 m in the evening, southeast Lanzarote at 3 – 41 m depth during the day and west of Gran Canaria at 42 – 66 m depth at night. Larvae occurred also at epipelagic stations north of Gran Canaria at a depth of 55 – 90 m at night and southeast of Fuerteventura at a depth range of 90 – 107 m during the morning.
